If starting of equally sounding by learning key just plays the sound of other three parts in addition to part is arranged after clapping, because
For be arranged at this time part need student participate in playing (if still played the part sound will with the vocal clash of performance shadow
Ring study), the keyboard of prompt setting part plays phoneme when keyboard indicator is with playing；Charactron 08 at the end of performance
Its last score (1-100) is calculated and be shown in the ratio for the correct note that can be more played according to study, and thus, it is possible to timely by student
The performance degree for being clear from oneself or progress situation, effectively promote its next time study play in more energy concentrate,
Always make to learn more efficient in the excitatory state in a kind of expectation.Thus mode student can learn each in MIDI melody
Then the performance of a part can carry out band and instrumental ensemble training.
(instrumental) ensemble key is pressed, needs four or four groups of students at this time, it is melody, harmony, bass or group that respective qin, which is respectively set,
Then (instrumental) ensemble key is pressed simultaneously by drum sound portion, equally start to play starting bat, originate each sound that the broadcasting after clapping shields MIDI
Portion does not play the sound of each part automatically, each part requires student's performance and generates at this time, but equally has key at this time
The key of disk indicator light prompt setting part is played；Respective score can be equally shown after having played；Although four people or four groups
The content that student plays is different, but the rhythm of timing node is identical, and performance is exactly the effect that band instrumental ensembles out, to realize
A kind of teaching purpose of band's training.
In summary as can be seen that being played to the study of each part respectively and band's conjunction from complete four parts
The training played, starting bat are the indicator light prompt key performances all one that identical, each sound plays (accompaniment) identical, each part
One is identical, so the qin efficiency of student is very high, makes rapid progress, the training for instrumental ensembling band does not have apparent threshold.

Five degree and low 5 degree designs compare with 6 the degree of height of Fig. 1 to be more convenient to move up and down enter a new line performance melody and arpeggio, but not
Foot place is the descant of range scope and double bass is all each has lacked a naturetone.
Fig. 1 is compared with two kinds of scale arrangement designs of Fig. 2, and the arrangement of key up and down that Fig. 2 differs five degree is more suitable for primary student
Study, and Fig. 1 height differs the study that six degree of design is then more biased towards suitable higher grade pupil.
It please see Figure 3, this is that a kind of acousto-optic of one embodiment of the method for classroom musical instrument band training of the invention is synchronous
Steps flow chart schematic diagram,
In figure [broadcasting] be program scanning to play instruction i.e. play starting clap, and judge play starting bat before whether
There is key command to select melody part (then program default choice is provided with melody part without key command), if so, defeated
The keyboard of melody part plays light indicating signal out, while playing the complete melody currently selected, i.e. four parts of band
Performance.
If it is not, i.e. Programmable detection is provided that harmony part to before playing starting bat, the keyboard of harmony part is exported
It plays pilot light signal and plays complete melody simultaneously.
If nor the harmony part of setting is provided that bass part, the keyboard of output bass part play indicator light
Optical signal, while playing complete melody.
If the keyboard performance in output shelf drum sound portion refers to nor the bass part of setting is provided that frame drum part
Show light signal, while playing complete melody.
The broadcasting sound of various part selections is all identical in figure, i.e., four parts play simultaneously, the difference is that in advance
It is provided that study (study of audiovisual) the key indicator light of that part indicates that learner was both with regard to the performance of that glittering part
It has heard complete whole song, and can have been understood while music rhythm carries out according to the prompt of light signal and recognize current sound
The specific performance position of piano key in portion；It is allowed in hearing this band performance's sound understand part selected by discrimination by light indication signal
Performance, i.e., simultaneously have the signal of the sense of hearing and vision support keep Music perception more intuitive more efficient.
[study] the i.e. learning process of monophonic in figure is judged as after startup program and plays starting into learning state
It claps, subsequently determines whether pre-set be melody part, if so, i.e. MIDI, which closes melody part channel, plays other three sound
The sound in portion channel, while the light indicating signal for playing melody part is exported, student can be with the prompt of key indicator light
Play melody, while MCU program detect one by one each performance key (phoneme) it is whether identical as standard value, it is identical to point,
Not identical do not give is divided, and is exported the aggregate score of the display study performance song melody part after study by charactron, is scored
For hundred-mark system；
If pre-set is not melody part but harmony part, program starts the process of harmony part, and midi is closed
Instruction optical signal is played in the broadcasting for closing harmony part channel, the keyboard for exporting harmony part, MCU program detects the sum played one by one
Whether several qin sounds (phoneme) are identical as standard harmony qin sound, and identical give is scored, different not to score, study knot
The study score for showing the song harmony part is exported when beam by charactron；
If being provided that bass part, program starts the process of bass part, and midi closes broadcasting for bass part channel
The keyboard for putting, exporting bass part plays pilot light signal, while MCU program detects the key (phoneme) of each performance one by one and is
No identical as the bass qin sound of standard, same identical give is scored, different not to score, again by number at the end of study
Pipe output shows the study score of the song bass part；
If be arranged is not melody part, is not harmony part, nor bass part but group drum is frame drum part,
The then step process of program frame drum part, the broadcasting in midi closing group drum sound portion channel, the keyboard in output group drum sound portion are played
Indicate optical signal, while MCU program detect one by one each performance key (phoneme) it is whether identical as standard value, it is identical to give
Score, it is different not to score, the study score for showing the song group drum sound portion is exported at the end of study by charactron；
[study] in Fig. 3 is although be the performance study of monophonic, and student is to instrumental ensemble the i.e. more sound of sound equipment in band always
Learn the performance of each part in portion's sound equipment, so the experience that study is played is still the learning experience in entire band's He Zou,
It is equivalent to carry out a kind of potential band's He Zou training.
The learning process step that [He Zou] i.e. band in Fig. 3 instrumental ensembles, needs for student to be divided at this time per four-handed
Cooperative training.
It is judged as that starting is played into (instrumental) ensemble state claps after startup program --- which part judgement is provided that, if
If the performance that melody part is output melody part indicates that optical signal or harmony part just export the performance instruction of harmony part
If if optical signal or bass part just export the performance instruction optical signal of bass part or organize drum (frame drum) part just
The performance in output group drum sound portion indicates optical signal --- the MIDI zero passage output i.e. melody part channel of MIDI, harmony part are logical
Road, bass part channel, frame drum part channel are all closed and are not played, and each part is generated by the performance of classroom musical instrument respectively
To achieve the purpose that training is instrumental ensembled by band.
Each qin is played without the sound in any channel in instrumental ensembling step, but the performance of each qin has respective setting
The optical signals such as the performance instruction of part, the instruction optical signal and the instruction optical signal of broadcasting step and learning procedure before are one
Sample, that is, known performance indication signal before student, so He Zou is got up, each part is not all strange, Mei Gexue
Life can distinguish whether four parts of four people of this group are correct or are in the main true from sound equipment, return so as to timely correction or again
The study of monophonic is reviewed to previous step, then from the beginning starts band's training of four parts again, thus back and forth, classroom is happy
The band of four part of device (can certainly be more multi part) instrumental ensembles training and just reaches an ideal teaching efficiency.
Fig. 4 is the rhythm warning process schematic diagram of the method for one embodiment of the invention, starts to detect as shown, powering on
The duration error of key input, i.e., the note one by one played student is with the duration of preset standard note compared with pair, if detecting
Be greater than right value (i.e. performance speed partially slow) to the duration of qin sound is played, orange luminescence pipe start it is glittering, if detecting performance qin
Sound duration is less than right value (i.e. performance speed fast), and red luminotron is glittering, if detecting key qin sound error amount
It is judged as correctly equal to right value (the duration deviation that positive negative error 1/5 is clapped can be set and belong to right value range) without sending out
Light signal allows student that can know oneself in time in study playing procedure to generate a kind of visual effect of rhythm warning
